Objectives : The objective of this research is to look deeper into the thoughts of Sajudang in her book on fetal education, Taegyoshin-gi(TGSG), published in the early 19th century Joseon, which focused on her understanding of human development and bodily relationship the mother has with her child with comparison to Korean Medical texts. Methods : The characteristics of TGSG were laid out with comparison to previous texts on fetal education of both China and Korea. After this, they were closely cross-examined with Korean Medical thoughts on human creation, mother-child relationship, and mind-body relationship. Results : Sajudang's thoughts on fetal education as written in TGSG, show a deep understanding of human development and the father and mother's roles in it, expanding the responsibility of fetal education from just the mother to both father and mother. There is also awareness of the importance of the Heart that is at the center of the fetal education process, and of the mother-child relationship through blood. Conclusions : Fetal education as discussed in TGSG expands from previous discourses on the topic, distinguishing itself with thorough understanding of how fetal education works, when it begins, and what the roles of the parents and the community are. This attributes to Sajudang's knowledge that came from both books and her actual experiences.

A project planning is one of the most important processes that determines success and failure of the project. A pre-project planning is also essential job for information system implementations at the early stage of project planning, especially for management information system like ERP. However, pre-project planning is very difficult, because lots of factors and their relationships should be considered. Pre-project planning of ERP implementation has been done by project manager's own knowledge and experiences. In this article, we propose a system that help project manager to make a pre-project plan of ERP project with case-based reasoning(CBR) framework. The proposed CBR system saves previous cases of ERP pre-project planning in the case base. Then, the system finds the most similar case with the current pre-project planning problem. Project manager can make a pre-project plan by adjusting the most similar case. From the interview with project managers, we collect some field cases of ERP implementation. We organized these cases by using XML(Extensible Markup Language), which is good for representing hierarchical information. XML gives us some flexibilities to correct and maintain cases. We make a prototype system, PPSS(Project Planning Support System) that help project manager to make a pre-project plan of ERP implementations. The object of the system is to support project manager to make a pre-project plan of ERP. We hope the result of the study can be applied to other information systems. Our research would be extended to cover other stages of project planning.

Background: Maxillary sinusitis of odontogenic origin, also known as maxillary sinusitis of dental origin or odontogenic maxillary sinusitis (OMS), is a common disease in dental, otorhinolaryngologic, allergic, general, and maxillofacial contexts. Despite being a well-known disease entity, many cases are referred to otorhinolaryngologists by both doctors and dentists. Thus, early detection and initial diagnosis often fail to detect its odontogenic origin. Main body: We searched recent databases including MEDLINE (PubMed), Embase, and the Cochrane Library using keyword combinations of "odontogenic," "odontogenic infection," "dental origin," "tooth origin," "sinusitis," "maxillary sinus," "maxillary sinusitis," "odontogenic maxillary sinusitis," "Caldwell Luc Procedure (CLP)," "rhinosinusitis," "functional endoscopic sinus surgery (FESS)," "modified endoscopy-assisted maxillary sinus surgery (MESS)," and "paranasal sinus." Aside from the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) trial, there have been very few randomized controlled trials examining OMS. We summarized the resulting data based on our diverse clinical experiences. Conclusion: To promote the most efficient and accurate management of OMS, this article summarizes the clinical features of rhinosinusitis compared with OMS and the pathogenesis, microbiology, diagnosis, and results of prompt consolidated management of OMS that prevent anticipated complications. The true origin of odontogenic infections is also reviewed.

Multiple choice items have been widely used. However the difficulties in understanding and solving the items have not been known well. The purpose of this study is to analyze the difficulties and errors in the process of solving multiple choice items. Twelve multiple choice items were developed based on the Unit 5 Separation of Mixtures in the 4th grade. Four items which students had hardly given the correct answer were selected and six students were chosen for interview. Interview results were analyzed with regard to the errors in the process of solving the multiple choice items. The findings of this study are as follows: I) The students who misread and misunderstand the questions choose the incorrect answers. 2) Most of the students activate daily knowledge in the process of problem solving. 3) The students who have misconception with the daily knowledge or have no experiences choose incorrect answers, while students who activate both daily knowledge and school knowledge choose correct answer. 4) The students of high level commit errors mainly in the latter part of problem solving process, but the students of low level do from early.

Objective: The purpose of this study was to investigate the relationships among mothers' play beliefs, children's gender and home play frequency, and their preferences for three types of play. Methods: Totally 256 mothers of 5-year-olds participated in the survey in metropolitan area. Data were analyzed with t-test, Pearson's correlations, and stepwise multi-regression using SPSS 22.0. Results: First, boys and girls showed little difference in their home play experiences. Boys preferred active and rough play, while girls preferred quiet play. Second, mothers' play beliefs and children's home play frequency had partial correlations with children's play preferences. Third, predictors of children's play preferences were influenced by the types of play. Children's gender and mothers' play beliefs affected children's preference for active play. Only gender explained children's preference for rough play. Finally, children's gender, home play frequency, and mothers' play beliefs influence children's preference for quiet play. Conclusion: In conclusion, gender is an important factor of children's play preferences, and mothers' play beliefs and children's home play frequency affect their preferences for a specific type of play.

The purpose of this study was to examine the life satisfaction of adolescents in the ecological contexts of their individual, family, school, and social-cultural experiences. The participants were 1,099 middle and high school students in Chungnam-do. Instruments were the Satisfaction with Life Scale, Rosenberg Self-Esteem Scale, Parent-Adolescent Communication Inventory, the School Life Satisfaction Scale, and Social-Cultural Satisfaction Scale. Data analysis involved the use of descriptive statistics, t- and F-tests, Duncan's multiple range test, product-moment correlations, multiple regression, Cronbach's ${\alpha}$, and factor analysis. Results were as follows: Firstly, middle school students showed the highest levels of life satisfaction, and vocational high school students reported the lowest levels. Also, life satisfaction was inversely related to school grades. Secondly, for all the students, life satisfaction was positive correlated with self-esteem, open communication with parents, school life satisfaction, and social-cultural satisfaction. Lastly, open communication with parents and overall satisfaction with life at school explained more of the variance in adolescent life satisfaction than any other factors.

Objectives Experience of early childhood abuse elevates the risk of developing schizophrenia in later period of life, incidence of psychiatric comorbidity, symptomatic severity and complexity. In this context, we hypothesized that the pattern of psychotropic medication used would reflect this; those with childhood trauma will received more types and higher doses of psychotropic medication. Methods From our database of 102 outpatients diagnosed with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) schizophrenia, we analyzed experiences of childhood trauma measured by the Childhood Trauma Questionnaire-Short Form and types and dose of prescribed psychotropic medication. Results We found significant positive correlations between child sexual abuse and the number of psychotropic medications (p = 0.029) and between child emotional neglect and the number of psychotropic medications other than antipsychotics (p = 0.045). Conclusions This preliminary study suggests that the pattern of psychotropic use may be affected by types of childhood trauma. Further studies will have to shed light on mediating factors such as symptoms or comorbid conditions that lead to prescription of certain psychotropic class.

This study surveys 212 accounting information systems (AIS) of 85 manufacturing firms by using the research model based on the management process of AIS to figure out the current status and problems of the computing environment and AIS of Korean firms. The analysis of the current status leads to the suggestions to promote the utilization and efficiency of AIS. The level of experiences and education of information system (IS) personnel turns out to be still low. More education is needed to upgrade the IS personnel. AIS users lack in the computer knowledge. The users need more computer education. The analysis on the computerization and information characteristics of the AIS subsystems shows that the computerization is well established in the financial accounting area. On the other hand, the computerization for managerial accounting areas is in its early stage. The managerial accounting systems need be developed to support the managerial decision making effectively. The majority of firms develop the AIS by their own IS teams. When firms use the consulting services in developing AIS, they prefer accounting firms. The majority of firms fail to evaluate the AIS because the evaluation tools are not available. Most firms do not perform the auditing for AIS. It is needed to develop the tool and techniques for evalauation and auditing AIS.

The purpose of the paper is to examine the nature of population distribution during the past 25 years; to evaluate effect of population redistribution policies which have been adopted by the government; and to suggest desirable future policy directions. The distinctive features of population distribution during the period of 196O~85 can be summarized as progress of rapid urbanization, decrease of absolute number of rural population and heavy concentration of population in the Seoul metropolitan area which have resulted in population maldistribution among regions. The problem of population concentration in the selected one or two large urban centers was first recognized by the government as early as in 1964. Since then numerous policy measures have been adopted to reduce the population concentration into the Seoul metropolitan area and thus to guide a sound population redistribution among regions. The overall assessment of various policies on population redistribution, however, revealed that the effect of the policy efforts has not been great as they originally anticipated. Various reasons can be cited for the failure of the past policies. Among them the followings were frequently mentioned; lack of integration among policy measures; weak linkage between relocation and accommodation; and non-existence of single authority for overall implementation of the polices. Based on the past experiences the followings are suggested in pursuing future policies. First, the short-term objective or target should be clearly defined. Second, policy measures have to be designed to go with rather than against market forces. Third, indirect incentives or aids are more effective than direct controls or regulations. Fourth, local participation has to be secured in every phase of policy formulation and implementation.

Objective: This study aimed to examine the difference in toddlers' accumulated cortisol levels based on childcare experience in toddlerhood and the relationship between temperament and accumulated cortisol levels. Methods: Hair sample were collected for measure accumulated cortisol level in 87 toddlers. The Early Childhood Behavior Questionnaire (ECBQ) was used to measure temperament. Results: First, toddlers in childcare showed higher accumulated cortisol levels than in-home toddlers. Second, toddlers in childcare, exhibited a significant correlation between accumulated cortisol levels and surgency. Third, the accumulated cortisol levels of in-home toddlers exhibited a significant correlation with negative affect. In this research, there was significant range in the accumulated cortisol level according to childcare use, and the factors related to accumulated cortisol levels were different in each context. Conclusion: The results of this research support the "susceptibility to context of HPA axis" and imply a needed discussion about the effect of childcare experiences in toddlerhood.
